Still seeking 3B2 information

[Alan Hightower]

Yes thank you Al. Those have been a huge help in understanding the
Common I/O design most of the peripheral cards were built around. 

To shadow Seth's request, I'm looking for a few card ROMs I do not have.
Specifically if anyone has ROMs for the following 3B2 cards: 

CM195A NI Network Interface (10Mb Ethernet AUI)
CM195AE SPSC Gen. Purpose Synchronous Controller
CM195W SCSI SCSI controller
CM195T ISC Intelligent Serial Controller
CM195K XDC Expansion Disk Controller
FXM Fiber eXpansion Module
CM195AC/AD DKIT "Datakit" fiber-optic card 

I would really appreciate a dump. One of my goals is to work towards a
hardware emulation project of one or more of those cards. eg NI -> WiFi
or 100BaseT, SCSI, XDC, or CTC to SD card or USB host, PORTS/EPORTS to
USB virtual com port. 

I'm been staring at 80186 ROM dumps from the CTC, PORTS, EPORTS, and NAU
over that last few days. Even though they are all based on the same
(horrible) software framework, it would be nice to have a few more for
comparison. 

Thanks.
